The 4H0 121 671D Heater Control Valve by Febi Bilstein is an OE‑quality replacement for the heater coolant valve used on various Audi and VW models. Installed in the heater circuit, this valve regulates the flow of hot coolant to the heater core so your climate control system can deliver consistent, adjustable cabin heat.
When the original valve fails, you may notice weak or intermittent heat, different temperatures from left/right vents, or small coolant leaks around the valve body or hose connections. Replacing it with this Febi 4H0121671D unit restores proper coolant flow through the heater core and keeps your HVAC system performing like it should.
(Always confirm compatibility with your VIN or by matching the original part number before ordering.)
